To all whom t may concern:

Be it known that I, WILLIAM E. ANDRE, a citizen of the United States,residing-jat Chi'- cago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Mangles; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same. A

My invention relates to a novel construction in a mangle of that classin which the garments to be ironed are passed between a padded cylinderand steam-chests, and has v'for its object to provide simple andl'efficient means for moving the steam-chests into and out of contactwith said padded cylinder; and it consists in the features ofconstruction and combinations of parts hereinafter fully dekp 10, 11,and 12, said gearing being duplicated scribed and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is afront elevation, partly in longitudinal section, of a machineIconstructed in accordance with Inyinvention. Fig. 2 is an end elevationof same, the gearing being removed and the steam chests shown out ofaction. Fig. 3 is a vertical transverse section on the line 3 3 ofFig. 1. Fig. 4 is a fragmentary detail section on the line 4 4 of Fig.2.

Machines of this class are particularly designed to irontablecloths,-sheets, napkins, &c., which generally are not starched, andhence do not require the same degree of pressure as starched fabrics. Insome cases, however, such articles are starched, and in such instancesit is essential that the steam-chests be movable a sufficient distancefrom the cylinder to provide ampleroom for cleaning the inner surfacesof the chests, the starch being apt to adhere to same andform dryclots,which greatly hamper the ironing and frequently cause the articleto be ironed to bunch up and clogthe machine. It is not only necessarythat'the'steam-chestsbe movable for a considerable distance, but it isequally essential that the devices controlling same be rapidly operativeand at the same time afford efficient means for obtaining the requisitepressure of the steam-chests against the cylinder when in action.

'ply of steam. Vder 5 is mildly heated to an extent suflicient `t0 keep'the padding 6 perfectly dry. The ,said shaft 4 is suitably geared to asource of `My` present invention "relates particularly to the last-nameddevices, which I Will now proceed to describe.

Referring now to said drawings, 1 indicates the end pieces of the frameof the machine,

which tare suitably connected by trusses 2.

The said end 'members 1 carry the journalboxes 3, in which the hollowshaft 4 of a hollow cylinder 5 is journaled. The said cylinder 5 isperforated and is completely covered with padding ofany suitablematerial.

Said cylinder 5 carries several coils of pipe 7, connected with saidhollow shaft 4, the latter being suitably connected with a source ofsup- In this manner the said cylin oWer by means of the pulley 8 andgears 9,

at both ends of the machine to avoid torsional strains and providegreater strength. Said Yend members l'of the` frame are provided at eachside with arms l'and 14, each carrying an enlarged guide-rail15 at itsupper end,

which extends radially to the shaft 4. On each of said guide-rails 15ashoe 16 is movable, thelatterbeing integral with and projecting fromeach end of each of the steamchests 1 7 and18. The said shoes 16 eachconsist of a flat iiange resting upon the said guiderail 15 or uponaplate 19, loosely mounted in' said shoe and sliding lon`saidguide-rail, said plate being used for purposes'of adjustment by means ofa set-screw, as will be obvious. To the outer edge of said flange adownwardlyextending L-shaped plate 20 is secured,which engages the outerand one of the lower faces of the guide-rail15 and serves topreventlateral movement betweenthe` latter and the shoe. Formed betweensaidshoes 16 and the ends of the steam-chests 17 and'18 are pockets 21,open on their outer and lower ends and provided on their inner Wallswith openings 22, the inner faces ofthe said'inner Walls of.

IOO

formed that their inner or contact faces are of the same contour as theouter face of the cylinder, so that when in action said inner faces willbear upon the padding G equally at all points. One of said chestscarries a receptacle 24, adapted to receive the articles to be ironed,and the other thereof carries a table 25, adapted to receive the ironedarticles. The said chests when in action cover about two-thirds of thesurface of the cylinder, their lower edges being close together at suchtime. 'lhe said chest 18 is beveled on its inner face at its lower edgeto prevent the end of the article operated upon from bunching at thispoint, as will be obvious.

Theguide-rails l5 are inclined downwardly, so that the natural tendencyof the steamchests will be to move away from the cylinder. -Hence littlepower is required to throw the chests out of action. The said chests areoperated by means of collars 2G, revolubly mounted on the journal-boxes3. Each of said collars is provided with two projections 27 and 23 onits periphery, located about one hundred and ten degrees apart, and tosaid projections arms 29 and 3() are pivotally secured. Each of saidarms is curved concentric with said collar adjacent its connection withthe latter and terminates in a straight end 3l, extending radially fromsaid curved portion. Said straight end portion 3l of each arm passesthrough the opening 22 in one of said pockets 2l and is provided at itsouter end with a nut 32, threaded thereon, between which nut and saidinner wall of said pocket 2l a spring 33 is interposed. Said spring 33bears at one end upon the ribs 23 on said inner wall of said pocket,said ribs acting as a fnlcrum upon which the spring can turn. The saidopenings 22 are also of such size relatively to said end portions 3l ofsaid arms as to allow the latter considerable play. When saidsteam-chests are in action, the end portions 31 of said arms extendpractically radially from said collars at points diametrically oppositethe connections of said arms with said collars, while the curvedportions of said arms embrace said collar, said arms being held a littlepast dead-center by the engagement of said curved portions thereof withsaid collars. By turning said collar in one direction the said arms willbe turned on their pivots and thrust outwardly therefrom, thus throwingthe steam-chests out of action, and by turning said collar in theopposite direction the steam-chests will be drawn in con tact with thecylinder.

I desire to call particular attention to the fact that in drawing thesteam-chests toward the cylinder the arms are given a sweeping stroke,little power being required for the main part of the movement, whileduring the last portion of the stroke the leverage obtained increases,so that the desired pressure of the steam-chests against the cylinder iseasily obtained.

Attention is further called to the fact that by means of the formationof the arms 29 and 30 the disks or collars 26 are held a little pastdead-center'when the steam-chests are in action, thereby obviating theuse of additional locking means, while at the same time the pressurefrom both sides on said disks or collars is equalized, which isobviously very advantageous. Through the medium of the springs 33 thepressure of the steam-chests against the cylinder is rendered yielding,so as to readily accommodate various thicknesses of fabrics to beironed. Each of the said collars is operated by means of an arm 34-thereon, to which a rack-bar 35 is pivotally secured at one end, saidrack-bar meshing with a pinion 36 on a shaft 37, journaled in the lowerends of the end members l of the frame, heilig held in mesh with saidpinion by means of an idler 38. Mounted on said shaft 37 is aratchet-wheel 39 and adjacent same a lever 40 is loose on said shaft,said lever being provided with a spring-actuated dog 4l, engaging saidratchet-wheel, and which is operated to throw same into and out ofengagement with the latter by means of a hand-lever 4t2 on said lever40. A second ratchet-wheel 43 is rigidly mounted on said shaft and isengaged by a pawl 44 on the frame, said last-named ratchet-wheel andpawl being adapted to further lock the steamchests in position againstthe cylinder, said locking devices being provided foi-,greater safety.By means of the lever 40 said shaft 37 may be turned in either directionwhen the pawl 44E is thrown ont of engagement with the ratchet-wheel 43,as will be obvious. The said steam-chests are thus easily and quicklyoperated.

I claim as my inventionl. In a mangle,tl1e combination with the cylinderand the frame carrying guides, steamchests supported upon and movable onsaid guides toward and away from said cylinder, of disks revolublymounted on said frame concentric with said cylinder, projections on saiddisks, and arms pivotally connected at one end with said projections andat their other ends with said steam-chests, whereby when said disks arerevolved said steamchests will be moved.
